javascript - 按空属性/条目过滤对象

Question

如何过滤对象，例如:

{"firstname":"foo","lastname":"bar","driving":"","overnight":""}

至

{"firstname":"foo","lastname":"bar"}

仅删除空键/值对

Answer 1

使用 Object.keys() 和 Array.prototype.forEach() 的解决方案:

var original = {"firstname":"foo","lastname":"bar","driving":"","overnight":""};
var filtered = {}
Object.keys(original).forEach(function(key) {
    if (original[key] !== "") {
        filtered[key] = original[key];
    }
});
console.log(filtered);
